Parking Court, Modular Wall, Plants

I don't know if this is going to work. Obviously this is a rendering for a front yard where the main elements are this new wall, the parking spaces now available because of the new wall, and the diversity of the planting(s).

The conifer screen is good and the anchor plantings along the wall base. What is now bugging me are the "standards" above the wall that appear to be placed in the mass planting. It shows some rhythm and harmony, but I now wonder about the appropriateness, and aesthetic. client is looking at this and others on Friday, we will see.
